Field of the Invention This invention relates to riveting. More particularly, it relates to simplifying riveting by providing a combination of a slanted horizontal riveter with a turntable.

2. Description of the Prior Art Horizontal riveters are known, for example, those of US. Pat. Nos. 3,890,014 and 3,562,893. Nevertheless, up until now it has been conventional in the art to use a vertical riveter, which requires an operator to place each individual location where the rivet is to be applied on the anvil by moving the article to be riveted by hand every time a new rivet is to be used. This is, of course, a rather laborious and time-consuming operation.

SUMMARY OF THE INVENTION After extended investigation we have found that the riveting operation can be considerably simplified by combining a horizontal riveter positioned substantially parallel to and slightly above the surface of a turntable. Both are slanted at substantially the same angle from the floor or regular table surface in order to facilitate guiding of the turntable by an operator when he moves it for exact positioning of each individual rivet in the article to which a lining or such is being applied.

We prefer to use our slanted riveter-tumtable combination for fastening lining to brake shoes, although it will be apparent from the more detailed description which follows that this combination may also be used for any kind of routine or conventional riveting operation. In a preferred embodiment of our invention, knobs project from the surface of the turntable for insertion through the holes of the brake shoes or other objects having linings or the like applied thereto by means of rivets. These knobs or projections from the turntable, in addition to steadying the shoes or other objects which are having lining, for example, applied thereto, also make the turntable easy to rotate by hand. The riveter may be conveniently operated by a treadie or like floor pedal arrangement underneath the table. However, any conventional type of pneumatic or like arrangement for operation of the riveter may be used according to the invention. Additional projections from the turntable may be used, if desired, at intervals convenient for steady positioning of the brake shoes or other articles to which the lining or like material is being riveted. These may be conveniently of a smaller size than the projections which are inserted through the holes in the brake shoes when brake shoes are being lined.

A second protrusion of the size of a second hole in a brake shoe, when brake shoes are having linings riveted thereto, may be employed, if desired. This speeds up the riveting operation since the operator can put another brake shoe in position at thesame time he is applying rivets to the one already in position.

BRIEF DESCRIPTION OF THE DRAWING AND DESCRIPTION OF THE PRIOR ART For a better understanding of the invention, reference will now be made to the drawing which is illustrative and which forms a part hereof (FIG. 1).

In the drawing, an operator l inserts, one by one, rivets 12 which fasten a brake lining 14 to a brake shoe 16, by pressing pedal 18 connected to horizontal riveter 20 by hoses 22 so as to pneumatically operate riveter 20 hammer 24 against anvil 26. Operator 10 moves shoe 16 with lining 14 placed thereagainst from one riveting position to another by simply turning turntable 28 as he operates horizontal riveter 20. Brake shoe 16 is conveniently held in position, as operator 10, as he works, turns turntable 28 either clockwise or counterclockwise, by having an upward projection 30 from turntable 28 extending through at least one hole 32 near the end of shoe 16. Additional smaller upward projections 34 may be used by the operator to rotate turntable 28 or for holding an additional shoe and liner (not shown) in place prior to turning it on table 28 into the position shown occupied by shoe l6 and lining 14.

While the invention has been described in terms of preferred embodiments, the claims appended hereto are intended to encompass all embodiments which fall within the spirit of the invention.

Having thus described our invention and certain preferred embodiments thereof, we claim:

1. A riveting process which comprises riveting brake linings to the outer convex surface of brake shoes placed on a turntable, rotating said turntable such that rivets are applied during said rotating in successive order. and applying said rivets to said brake linings during said rotating by operation of a treadle or foot pedal, whereby a hammer, pneumatically acts against an anvil, thereby inserting said rivets through said linings and into said shoes as said rivets are applied one after another in an arc line along said outer convex surface such that said lining is snugly attached to said surface of said brake shoes, said hammer and anvil being positioned at an angle from horizontal, said turntable being positioned at substantially the same angle from said brake shoes and being substantially parallel to said turntable and said brake shoes being held in place during said applying of said rivets by insertion of at least one projection from the upper surface of said turntable through at least one hole in each of said shoes, thereby allowing the application of each rivet in a different location to be achieved by a rotary movement of the linings and shoes on the turntable.

2. A horizontal riveting device which comprises in combination, a horizontal riveter comprising a hammer and anvil slanted at an angle from ordinary table level and positioned above a rotatable table slanted at substantially the same angle as that of said horizontal riveter, said rotatable table having projections therefrom around the periphery thereof for positioning thereon one or more workpieces and one or more parts to be fastened to said workpieces along an arc line as said table rotates.

3. The horizontal riveting device of claim 2 wherein said rotatable table has projections from its upper surface for positioning of articles to be riveted.

4. The horizontal riveting device of claim 2 wherein said rotatable table has projections from the upper surface thereof adapted for insertion through the holes of brake shoes for holding them in position while having brake lining riveted thereto.

5. The horizontal riveting device of claim 4 wherein said rotatable table has additional projections from the upper surface thereof for steadying said brake shoes and brake lining or turning said table by hand while said brake lining is being riveted to said brake shoes.

6. A horizontal riveting device which comprises, in combination, a horizontal riveter comprising a hammer in the general pattern of the perimeter of said turntable, both said horizontal riveter and said turntable being slanted at an angle from horizontal and being substantially parallel to one another. 

1.
